Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a sling hook with an automatic opening device, and more particularly to an improvement in a hook for unloading cargo from a ship's warehouse.

[0002]

[Prior art]

 Conventionally, the sling hooks used in cargo handling operations on ships are lifted from the cargo hold (packed items are about 1.8 m in height), and when they arrive at the quay, workers use ladders, steps, etc. The person repeatedly lifts up the baggage, removes it with his / her hand, then gets off the baggage again and evacuates again and again, which is extremely hard work and takes time to complete. Was bad.

[0003]

[Problems to be solved by the invention]

 Therefore, this invention was developed to eliminate the above-mentioned drawbacks, and when the sling hook suspended load arrived at the quay and became unloaded, the sling (sling wire rope) was released. The aim is to develop a sling hook that aims to increase the efficiency of cargo handling work and reduce costs by providing a device that automatically disconnects from the hook to reduce worker safety and work time.

[0004]

[Means for Solving the Problems]

 Therefore, this invention was developed to eliminate the above-mentioned drawbacks, and when the sling hook's suspended load arrived on the quay and became unloaded, the sling (sling wire rope) was released. The aim is to develop a sling hook with a device that automatically comes off the hook.

[0005]

[Embodiment of the invention]

 Next, an embodiment of the preferred method of the present invention will be described with reference to the drawings. A sling hook is provided with a hanging body (1) which is hung on a rope (X) of a crane. A hook-shaped sling hook (2) is pivotally mounted near the lower end by a connecting pin (6), and a sling hook (4) is mounted near the connecting pin (6) of the sling hook (2) of the suspension body (1). The sling hook (2) is provided so as to press the inner end thereof, and the center of the suspending body (1) has upper and lower holes having a halfway projection and a substantially daruma hole communicating therewith. (Y) is provided, and one end of the holding body and stopper (3) is loosely fitted to the hole with the holding body support pin (7). A sling support pin (8), which is engaged with the hook at the tip of the sling (2), is fixedly provided. The holder (3) is provided with a projection (10) at the tip and a recess (9) at a position opposite to the projection of the suspension (1). It comprises a sling hook with an automatic opening device, characterized in that 1) and the holding body and stopper (3) are connected by a holding spring (5). Note that (11) is a sling and (12) is a suspended load.

[0006] Next, the operation of the present invention will be described. When suspending a load from a hold, first, an operator manually removes the sling hook (2) from the holding member and the stopper (3) and suspends the sling. The sling (11) for suspending the load (12) is hung on the sling hook, and the sling hook pin (8) of the holder / remove stopper (3) is engaged, and the holder / remove stopper (3) is pushed upward. As a result, the projection (10) of the holder and the stopper is fitted into the recess (9) of the suspension (1).

When the sling is lifted by a crane or the like, the sling hook (2) falls downward due to the load of the suspended load (12). The retainer support pin (7) of the stopper (3) moves substantially below the daruma hole (Y), and the retainer / remove stopper (3) is slinged (2) against the retaining spring (5). It is locked by the hook at the tip of the stairs and is stable, and carries the suspended load to the quay.

When the suspended load lands on the ground and the sling hook (2) is in a no-load state, when X) is lowered, the sling hook spring (4) operates, and the end of the sling hook (2) is closed. By pressing the inside tip outward, the sling hook (2) moves upward. As a result, the hook at the distal end is released from the sling support pin (8) of the holder / remover (3), and the spring (5) for the holder acts accordingly. It moves leftward in the drawing, so that the sling hook (2) is lowered and the sling (11) is automatically released from the sling hook.

[0009]

[Effect of the invention]

 According to this inventor, for example, when lifting from the hold, if the sling is manually set on the sling, the hook is automatically released after landing on the quay or the ground, which is safe and workable. This has extremely beneficial effects such as shortening the time.
